8yrs bedwetting - school trip - help!?

[FourHorseShoesoftheApocalypse]

My son is 8 and still wets at night - at home he wears a nappy but will often wet through it. He has school trip coming up in Spring so I'm looking for some absorbent pants that he could wear under his pyjamas that look like normal pants - has anyone tried these - one review on amazon doesn't sound promising, or does anyone know any other good products?

There are products available on the ERIC's website for this exact scenario.

Have you seen the GP about his bed wetting? I think that's usually advised once they get to 8.

Have you been to your GP? There used to be a nasal spray available which helped with bedwetting, know of a few boys prescribed this so they could go on school trips or on sleepovers with friends.
